Second component of Web architecture is the Web Listener
The second component of Web architecture is the Web Listener. The Web Listener is an HTTP engine, similar to an Oracle background
process, located on the Oracle host that manages incoming requests for services. Each host may have many listener processes
running, depending on the processing needs of the Oracle WebServer.
The Slide Show below describes the role of the Web Listener.
The Web Listener receives incoming requests
The Web Listener submits incoming requests in the web request broker for processing.
The Oracle data is retrieved and the web request broker builds the HTML or JSP page.
Web Request Broker hands the page back to the web listener.
The web listener then sends the completed HTML documents back to the originating requester.
